' Patented Apr. 22, 1930 1 PAUL 2B. emzmo'rrr, or UNION CITY, NEW mnsn PAPER PRODUCT Application filed February 18, 1929 Serial No. 839,563.

The subject of the invention is a. paper" product of nacreous aspect having utility for decorative purposes, such as wall-paper, lamp shades, book and box coverings, etc.

the product being of such character and structure thatthe nacreous to the presence of crystalloid bodies obtained from fish-scales, is developed in a new and effective manner. 4 a

The product consists of a translucent paper having a surface of extremely high or glassy finish thrown by pressure between dies ordierolls into a multiplicityv of sloping areas or corrugations, in regular or irregular em- 5 bossed designs, which surface, or surfaces, are coated with a translucent or transparent coating material containing the said. crystalloid bodies. These bodies of elongated spindle shape tend to follow the contours of the smooth, prismatic orembossed surfaces,

with the result that all slo es reflecting to' rilliant in con-- the eye of the observer are 4 trast to other areas, causing the pearly lustre to have an enhanced and changeable effect" differing from that which would be presented from a fiat surface. The paper texture and refractionat the upper and lower surfaces are involved in the result.

In the accompanying drawings, forming.

part hereof:

Fig. '1 is a plan .view of a piece of paperillustrating the invention; and Fig. 2 is a schematic sectlonal view on a much enlarged scale, noparticular attempt,

The paper sheet 2 is preferably one which is made of a strong sulphite stock, broken down'to secure the desired translucency or transparency,-and the desired smoothness of 40 surface under super-calendering or subsequent die'or die-roll pressure. By the d es or die-rolls the paper is thrown into embossings which cover the surfaces with projections and recesses, with or without some-flat 4 areas, producin multitudinous slopin areas, which lie at di erent inclinations to a ine of vision and tothe angle of incidence of light ra s.

{he or both surfaces of such a sheet is 6 coated with a transparent or translucent appearance, due

coating composition 3 containing pearl essence, that is to sa the herein mentioned minuteytransparen bodies recovered from fish-scales, such bodies having li ht reflecting and refracting, properties, w ich, When the bodies are incorporated in proper proportion in a suitable medium, produce a diffraction phenomenon which is similar .to that of natural pearls or'mother-of-pearl.

The coating medium is preferably a cellulose lacquer-, such as celluloid, cellulose nitrate, cellulose acetate, or the like, in a suitable solvent which evaporates for the most part from the coating. Other lacquers and varnishes, or casein compositions of fluid.

nature, may also be used. Such coating com-' positions are moisture and Water-proof and washable, making them suitable for wall paper, book coverings, and the like, or for coverings for contents affected by moisture.

If water-proofness should not be necessary,v

gelatine'or some other water-soluble material could be used as the coating vehicle.

The fish-scale crystalloid bodies are uni.-

formly incorporated in the coating medium.

by working or kneading, and the resulting composition is applied in fluid state to one or both surfaces or the herein described embossed, glassy paper, by flowing or by spraying, but preferably by the latter method.

The effect obtained with the product herein claimed is due to the light affecting properties of th'fish-scale bodies in a coating such as described, in combination with the natur-- ally brilliant, embossed, translucent paper foundation afiording formations whereby the light rays reflected from it and acting;

ance

through it from one side to the other e both the design and the pearly appearance of the coating. 4

The product may be composited with suitable foundation materials, so-called parchment and the like, as in the manufacture: of

lamp shades.

The particular form of design embossed in the paper is no part of the invention and a great variety of designs may be used. he coat-ing maybe tinted in any desired color by incorporating coloring material in the coating.

What I claim as new is:

v 1. As .a new article of manufacture, a

paper product for decorative uses comprismg a translucent paper of highly finished surface 5 thrown by embossing into a multiplicity of sloplng areas, and a'translucent coating covering one or both surfaces of said paper, said coating containing the crystalloid bodies obtained from fish-scales.

2(As a new article of manufacture, a

paper product for decorative uses comprising' a translucent paper of highly finished I surface thrown by embossing mto a multiplicity of sloping areas, and a translucent 15 coating covering one or both surfaces of said paper, said coating being on the order of a ,water-pi-oofed lacquer and containing the orystalloid bodies obtained from fish-scales.
